Hello!
To find the surface area of a cylinder you use the equation
SA is surface area
r is radius
h is height
PUt in the values you know
Square the number
Multiply 7 and 18
Multiply 126 by 2
Multiply the 49 by 2
Add
The answer is
Hope this helps!
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
